A methodological approach for assessing businness investments in renewable resources from a circular economy perspective
2018
Abstract In this paper, we have analyzed a feasibility project for the realization of a biogas plant at a company in the viticulture sector located in south-central Sicily. Using engineering formulas, we identified the electrical power that the plant could produce using waste products created by the vineyard itself, examined the new and interesting opportunities that have arisen with the encouragement and development of biogas production in Italy, and then assessed the economic feasibility of the investment itself, considering an investment scheme of total capital self-financing. The possibility of using wastes from wine production comes from an in-depth study of the circular economy, that …
Small Island developing states: Overview about wind, solar and marine energy in Cuba
2019
The current economic, political, and social trends in Cuba indicate that energy sector will change in the future. The energy consumption will increase and Cuba, like most island nations, lacks a large energy resource base and satisfies most of its energy needs with imported fossil fuels. The aim of this work is a summary of renewable energy sources (solar, wind, bioenergy and marine) presented in the island and the development in the next society of the future.
Valorization of Marine Waste: Use of Industrial By-Products and Beach Wrack Towards the Production of High Added-Value Products
2021
Biomass is defined as organic matter from living organisms represented in all kingdoms. It is recognized to be an excellent source of proteins, polysaccharides and lipids and, as such, embodies a tailored feedstock for new products and processes to apply in green industries. The industrial processes focused on the valorization of terrestrial biomass are well established, but marine sources still represent an untapped resource. Oceans and seas occupy over 70% of the Earth’s surface and are used intensively in worldwide economies through the fishery industry, as logistical routes, for mining ores and exploitation of fossil fuels, among others. All these activities produce waste. The other sou…
Urbanisation and Urban Regionalisation Processes in the Metropolitan Area of Palermo
2021
This article provides empirical evidence that helps to answer several key questions relating to the regionalisation processes in Southern European cities. Several studies have documented the effects produced by the urban regionalisation process, especially in terms of territorial resource consumptions and the formation of new territorial patterns, overlooking the evaluation of public information that has been lost in terms of space and prerogatives of public action in the new post- metropolitan urban space. Starting from this theoretical framework, the interpretation of the post-metropolitan transition of Palermo through the filter of living in its dual dimension of being the outcome of soc…
Shanghai Teachers’ Perceptions of Distributed Leadership: Resources and Agency
2021
Purpose:Drawing on distributed leadership and motivation theories, this study investigates teachers’ perceptions of resource and agency distributions and identifies the key factors motivating leadership among teachers.Design/Approach/Methods:This quantitative study collected data from 327 teachers in nine schools in Shanghai. Chi-square tests of independence were conducted to examine the associations between leadership structures and power distance, while Spearman’s correlation tests were used to identify changes in leadership resource impact. A nonparametric Friedman’s test was applied to detect discrepancies between the agency of principals, team leaders, and teachers. Finally, Chi-square…
Sustainable Regeneration of Brownfields
2016
Our cities are really rich of building ensembles now deserted which were, in the recent past, sources of job and productivity for the community. They are generally inside the urban fabric or in the suburbs and they are often not particularly taken into consideration because they haven’t architectonic characteristics which could justify a restoration. Due to their big extension, the planning approach turns to be diffucult. Besides, these areas, if adequately restored, could become an important economic and cultural resource and a possibility of experimentation of new sustainable technologies. All this heritage requires a planning approach based on conservation and valorization of all the cul…
The Projection of a Sustainable Agriculture System Aiming for Supporting the Ecoeconomy and Ecosanogenesis Specific for the Hill-Mountain Areas – Con…
2010
The Romanian integration into the European Union – and also at its technological standards – means among others the adoption and implementation of transforming measures into the conventional agriculture. Thus the farmers should apply certain technologies to enable them to obtain good productions under specific conditions of the ecoeconomy and ecosanogenesis. The implementation of such a sustainable agriculture system for Romania is discussed into this article.
L'enseignement interdisciplinaire de la littérature pour enfants écrite en anglais
2014
El objetivo de este estudio es el de elaborar una propuesta didáctica que maximice el tiempo y los recursos destinados a la enseñanza del inglés durante los tres ciclos que, en España, recibe la educación primaria, con alumnos con edades comprendidas entre los 6 y los 12 años. El método escogido para lograr dicho objetivo es la interdisciplinariedad, de tal modo que pueda lograrse la síntesis de contenidos pertenecientes a distintas disciplinas y áreas curriculares, en este caso a la “Enseñanza de una lengua extranjera” (inglés) y al “Conocimiento del medio natural, social y cultural”. El contexto práctico de esta propuesta, en cambio, es únicamente el conformado por las clases correspondie…
Music as a resource for psychological health for music professionals : A Nordic survey
2020
Purpose: Interest in the health relevance of music has been growing rapidly, yet few studies have addressed the protective role of music for music professionals themselves. In the current study, we investigated music professionals’ (music teachers, music therapists, musicians and academics) health, particularly their uses of music as a resource for their psychological health. Design: An online survey (N = 504) for music professionals was conducted across four Nordic countries. Participants responded to questions on music as a resource for psychological health and assessed their general levels of health and health behaviors. Their self-reported health was compared to similar prior data from …

This study is devoted to the research of human resources as a main source of sustainable regional development in Latvia. It is focused on two key concepts of human capital and migration. The aim of the study is to explore return migration geographies by looking at young return migrants as a resource and preconditions for sustainable regional development essential to Latvia.Return migration to the regions of Latvia is examined by two main research questions. What are the most recent return migrant characteristics in Latvia? How does return migration of young Latvians translates into regional geographies of return migration?Drawing on most recent available statistical data we elaborate on the…
